Coil design confines plasma in stellarator fusion reactor
|
Researchers from New York University have designed a configuration of coils for a stellarator, a type of device that controls fusion reactions. The shape, number and position of the coils are optimized to generate an external magnetic field for the stellarator that will prevent the hot plasma from deteriorating.

LCLS Beam Already in Action
|
The Near and Far Experimental halls are still under construction, but already scientists are putting the Linac Coherent Light Source (LCLS) beam to use. The LCLS electron beam, first generated in April, is now traveling from its source near Sector 20, through the Beam Switchyard at the end of the linear accelerator and into End Station A, one of SLAC's original experimental halls.

New light clock concept explains time dilation in special relativity
|
Joseph West, a physicist at Indiana State University, has recently proposed a method for intuitively visualizing and calculating the time dilation effects in special relativity—one of the stranger concepts in modern physics.

Electronic 'crowd behavior' revealed in semiconductors
|
Like crowds of people, microscopic particles can act in concert under the right conditions. By exposing crowd behavior at the atomic scale, scientists discover new states and properties of matter.

New start-up schedule for world's most powerful particle accelerator
|
Speaking at the 142nd session of the CERN Council today, the Organization’s Director General Robert Aymar announced that the Large Hadron Collider (LHC) will start up in May 2008, taking the first steps towards studying physics at a new high-energy frontier.

A sound way to turn heat into electricity
|
University of Utah physicists developed small devices that turn heat into sound and then into electricity. The technology holds promise for changing waste heat into electricity, harnessing solar energy and cooling computers and radars. "We are converting waste heat to electricity in an efficient, simple way by using sound," says Orest Symko, a University of Utah physics professor who leads the effort. "It is a new source of renewable energy from waste heat."

Scientists demonstrate quantum state exchange between light and matter
|
Quantum computers offer the promise of processing information much more efficiently than classical computers. But before quantum computers can be built, scientists must confront several challenges, one of which is quantum computers' vulnerability to their surroundings. Interaction with outside forces would immediately damage a quantum computer's information; this problem is known as "decoherence."
